TM 1-1670-260-12&P 0020 00 __________________________________________________________________________________________ 10. HOOK-UP AND RECOVERY FLIGHT OPERATIONS (Figure 1 and Table 3) WARNINGShould it become necessary for a ground crew member to perform hook-up while on the helicopter being recovered, extreme care must be exercised to avoid static electric shock, injury resulting from falling off the helicopter as a result of rotor downwash, etc. CAUTIONRemove any loose objects from recovery site to prevent them from becoming projectiles as a result of rotor downwash. NOTE Figure 1 details the disabled and recovery helicopter rigging. Reference numbers in the following text that are outlined in parentheses [i.e., (1), (2), etc.] refer to Figure 1, View A and Table 3 item numbers. Refer to Figure 1, View A and Table 3 for configuration guidance. a. Launch recovery helicopter. b. Direct recovery helicopter into hover position slightly to the side of the disabled helicopter where sling (8), Figure 1, View A, has been positioned for connection of the disabled helicopter to the recovery helicopter sling. WARNINGEnsure static grounding of recovery helicopter is accomplished by allowing free end of sling lines to touch the ground before ground crew comes in contact with sling. CAUTIONOnce sling line has come in contact with ground and after sling line comes in contact with a ground crew member, the crewmember must maintain continuous contact with the sling line until it is connected to the disabled helicopter to maintain static grounding. c. Allow end of sling line from recovery helicopter to make ground contact to discharge static electricity. 0020 00-13
